To all whom it may concern,.-

Beit known that I, JAMES R. GRAY, a citizen of the United States, residing in New York, in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Column-Caps, of which the following is a specification.

This invention relates to certain improve- 'ments in column-.caps for facilitating their connection with the I-beams supported on the columns below and with the columns supported on the caps. For this purpose the in- `vention consists in the novel features and combinations of parts, to be fully described hereinafter and iinally pointed out in the claims.

.in the accompanying drawings, Figure 1 represents a side elevation of my improved column-cap, showing the connection with the column below, the I-beams, and the column for the next story above. Fig. 2 is an end elevation, partly in section, on line 2 2, Fig.

1. Fig. 3 is a` horizontal section on line 3 3, Fig. 1.` Fig. 4 is a. perspective view of the semicircular inclosing sleeve for the upper column. Fig. 5 is a side elevation of a modiiied construction of column-cap. Fig. is an end elevation, partly in section, on line 6 6, Fig. 5. Fig. 7 1s a longitudinal section on line 7 7, Fig. 5; and Fig. 8 is a perspective view of the semicircularl sleeves shown detached from the column-cap.

Similar letters of reference indicate corresponding parts in the diferent iigures of the drawings.

Referring to the drawings, a represents the lower column, b a column-cap, which is provided at its lower part with a socket for connectingv with the upper end of the column a and with brackets b for supporting the I- beams d. Above the brackets b the columncap is provided with a cylindrical portion b2, at the upper end of which is formed a shouldered semicircular socket b3, in which and on the shoulder b4 of the middle portion b2 is su ported the upper column a', o'n which t e beams for the next story are supported. The wall of the semicircular socket b3, which is formed integral with the column-cap, is provided at diametrically opposite points with .flanges b5, to which are attached corresponding flanges e -of a semicircular sleev e-.by'

means of bolts e2 and nuts e3, thus forming a split separable sleeve in which the u per nolumn c is firmly seated. The tubu ar lower and upper'columns aa are filled with cement or other suitable material, so as to increase the strength of the same.

The middle portion b2 of the column-cap is provided at opposite sides with projecting lugs f, which are preferably cast integral with the middle portion b2, and -attached to opposite sides o f the I-beams d, which are sup-- ported on the brackets b of the columncap. The lugs f are reinforced at Atheir lower ends by tapering lribs f3, which strengthen the connection of the lugs with the middlef portion b2. y

In Figs. 5 to 8 a modified construction of the column-cap is shown. The middle portion b2 is in this construction not cast with a semicircular socket b3, but with a socketshaped extension i, having an exterior groove i To `this grooved extension i are attached two semicircular sleeves i2 i3, which form in conjunction a split sleeve, and are provided at their lower ends with inwardly-curved ribs i4, that engage the groove i of the socket i. The semicircular sleeves i? and i3 are further provided with interior raised projections,i5 at a point midway of their height and at their upper ends, which bind on the'lower end of the upper' column a as shown in Fig. 6, whenthe sleeves i2 i3 are fastened together at their diametrically-iianged ends by bolts i and nuts is, so as to form a rigid connection of the upper column with the grooved socket ,of the column-cap.. The iianges of the semicircular sleeves i2 i3 are reinforced at the upper end and lower end by tapering ribs i7.

By my improved column-cap the connection between the. column of the lower story and the beams and the column of the upper story can be made in a quick, strong, and effective manner by the bolting of the lugs on the column-cap to the adjacent ends of the I-beams and by the bolting together of the sleeves with the lower end of the next column above. ln this way the iron su porting-columns of buildings can be quick y reliably connected with the column-caps and the beams.

.Having thus described my invention, I

claim as new Iand desire to secure by Letters sleeve carried by said cap at the upper end thereof, and a column resting at its lower end' in said sleeveand clamped thereby. A 4 2. The combination, with a column, of a' ICO IOS

and a. member partially embracing the lowerend'of said last-named column and clamping the same laterally in said socket.

3. The combination, with a column-cap havinga semieircular socket at the topportion thereof, of a semieircular sleeve to coperate with said socket in positioning a column, and means to clamp said sleeve to the Wall of said socket. l

4. The combination, with 'a column-cap, of

an upright semiciroular Wallfolmed integral with the upper portion of said cap, said wall 15 being provided with flanved ends, a se'nn'eircular sleeve also provided with flanged ends, and means for connecting the flanged ends of said socket-Wall and sleeve. l

In testimonyT that I claim the foregoing as zo my invention I have signed my name in presence of two subscribing witnesses.
